Demodulation Processes in Auditory Perception.
Abstract
The attached interim report covers the first 12 month period of the project. A signal-processing computer model of human auditory perception of complex, time-varying sounds has been revised to incorporate the ability to follow a frequency that changes over time. Such frequency changes are thought to convey the information important for the perception of speech, music and other important sounds. Testing of the revised model is underway using a two alternative forced choice discrimination task. Listeners are required to distinguish between a sound with a smooth linear frequency glide and another covering the same trajectory in a series of discrete steps. We expect to determine the temporal parameters for the revised model from these discrimination experiments.
